Evaluation

lowest value from pretest:	280 °C
lowest value for first main test:	265 °C
lowest value for second main test:	263 °C
lowest value for retest:	265 °C

 

Lowest value of all main test/retest series: 263 °C.

Correction of the temperature according to the last DKD calibration (10/06/2014) of the temperature measurement chain (thermocouple + monitor) is already considered (value of -0.5 °C).

 

Concluding Result

The auto-ignition temperature is 260 °C (according to the assessment criteria and definition in the Council Regulation (EC) No 440/2008, test method A.15.

 

Conclusions:

An auto-ignition temperature of 260°C at 993 hPa was determined in a reliable study conducted according to an appropriate test protocol.
